I have recently purchased a couple of trucks with chalmers suspension and am in need of a little help. I am sure that someone has probably posted something on this before but cant find anything.
the problems that i am having is one of the trucks seem as the rear of the truck is drifting from side to side while driving down the road. We have checked all of the bushings and they all appear to be tight. the main "big rubber bushing" that is in the middle of the walking beam seems to have the most flexibility. Any ideas on what would be causing this? the other truck is not near as bad. I have thought about swapping the big bushing between the two trucks and see if the problem is transferred from one truck to the other. the chassis is a 2007 peterbilt bridgemaster mixer with a double frame and it has the same problem whether the bridge axle is up or down. Any help would be greatly appreciated. thanks ahead of time.:Banghead
